ELIZABETH A. PIERCE, CF ESCONAWBA, MICHIGAN, ADMINISTRA'IRIX OF SILAS L. PIERCE, DECEASED.

liVlPROVEiviENT IN CRE-CARS.

Specification forming part of Letters Patent No. l62,l89, dated April 20, 1875; application filed January 6, 1875.

To all lwhom fit may concern Be it known that S. L. PIERCE, late of Esconawba,in the county ofDelta and State of Michi gan, did invent a new and useful Improvement in Ore-Cars; and the following is declared to be a full and exact description ot' the same, reference being` had to the accompanying drawings, and to the letters ot' reference marked thereon.

This invention is an improved car, which is designed specially for conveying ore; and its novelty consists in the peculiar construction and combination of its parts, by means ot" Which it is adapted for the special purpose for which it is designed.

In the drawings, Figure l represents a longitudinal vertical section of the ore-car; Fig.V

2, a side elevation of the same, Fig. 3, a plan view ot' the dumping apparatus; Fig. 4, a modification.

To enable others skilled in the art to make and use the invention, I will now proceed to describe fully its construction and manner of operation. l

A A represent the sides of the body portion of the car, the same being constructed of suitable t'ralne-Work and boards, properlyT fastened together, and provided With the necessary braces and tie-rods to give it requisite strength. B B represent the end pieces, formed also of suitable frame-Work and boarding, properly braced and supported, which are inclined from the ends of the car at the upper edge to the edge ot' a discharge-opening centrally located in the bottom ofthe car, as shown. C C represent doors or naps ot' suitable construct-ion, which are united to the car about the sides of the opening by suitable hinge-joints, as shown. I) represents a sustaining-rod, which is itseltl supported above by a proper transverse bar, d, resting at its ends upon the upper edge of the sides ot' the car, and provided below with arms d d', adapted, when the rod is turned into one position, to extend beneath the free ends ofthe door or flaps and support the same., and, when turned into another, to release the doors and permit them to fall, for the purpose of discharging the contents of the car. E E E represent proper standards, three upon'each side,

by means of which the body portion of the car is connected to the wheels E E E. The car is also provided with suitable coupling devices and proper brake mechanism, as shown.

The manner of using the car will be readily understood from the foregoing description.

The doors being in their closed position, as shown in Fig. l, the Vcar is filled with ore in any proper manner, and conveyed by suitable means to the desired point. The sustainingrod is then turned, by means of a proper Wrench or handle, in such manner as to release the doors, by the falling of which the contents are discharged, the inclined ends guiding to the central opening such ofthe contents of the car as are supported by them.

The construction of the car is such as to give it requisite strength for the peculiar purpose designed.

The employment ot' intermediate central Wheels is exceedingly advantageous, because by means of them the Weight is more perfectly supported, and the car being less liable to spring and bound upon the track the tendency to ily from the track is almost entirely removed.

A car provided with an intermediate pair of Wheels is notbroadly claimed, nor such a car with means for dumping its contents from the bottom; but

Having thus fully described this invention, what is claimed as new, and desired to be secured by Letters Patent, is-

The combination ofthe body, having the sides, inclined ends B B, and the central discharge-opening, with the outwardly-swinging discharging-doors C C, the revolving supportin g-rod D, and the central Wheels', whereby the car is adapted to carry a heavy Weight steadily, and discharge the same through a central opening Without interfering with the central supporting-wheels, as described.

This specification signed and witnessed this lstuday of December, 1874.
